The HDP is a miniature HD-SDI/SDI to DVI-D converter for LCD or Plasma monitors. Using a very high quality scaling engine, the HDP will automatically size 4:3 or 16:9 inputs to many DVI-D monitors (see Technical Note below). For appropriate monitor configurations, scaling is automatically 1 to 1 - for example, displaying 1920x1080 video on a WUXGA (1920x1200) monitor. The HDP will also automatically adapt the input frame rate for monitor compatibility. In addition, the HDP provides 2 channel RCA style audio monitoring and 2 looping outputs of the SDI inputs. HDP is the ideal solution for displaying SDI or HD-SDI on any LCD or Plasma DVI-D monitor.

The HDP is designed to work with most DVI-D monitors. The HDP uses the industry standard EDID communication protocol (within the DVI link) to communicate with the monitor, and then adjusts the HDP's internal scaling engine to scale the input video to the native resolution of the monitor. However, due to the hundreds of variations of DVI formats currently in use, proper operation with all monitors cannot be guaranteed. The HDP has 2 modes of operation that occur automatically, depending on what monitor it is attached to. These modes are Recommended Monitor Mode or VESA Mode.
